I have the oppertunity to get a dual-snorkel from a '88 MPI Camaro. I have wanted one of those for ever, but could never find one.
Which is better performance wise?

 

Go with the dual snorkle if its from the H.O. L69.

 

Will a dual-snorkel's performance be noticable better than my single-snorkel intake right now?

 

Do you mean the Iroc air cleaner setup from a TPI ???

That is the best setup and attach it to your stock air cleaner without the sensor .

True ram air .

 

^Actually it is from an '88 Camaro w/ multi-port-injection
It has 2-intakes; it looks a LOT like the LS1 assembly; it curves downward by the radiator, and looks totally awesome

 

look at the first pic on page 2, that is a TBI 305 with a 2.8L MPI air cleaner

^Ya, that looks about it
But my air-cleaner is TONS bigger, lol.

 

yeah, so was mine, but I used the filters from the 2.8 air cleaner, and got the couplers, a piece of 3" pipe and the T/B "hat" from a 98 Dodge Dakota 3.9/5.2/5.9 engine

 

The Black V part of the air cleaner is what i was refering to ........best setup ........i'm looking for 1 for my TBI 305 .

 

Go dual snorkel Matt. Open element will actually suck in hot engine bay air and keep performance down. The dual snorkel will constantly get fresher, cool air from outside being that its closed in and air can only get sucked in from areas away from the hot engine bay air. Plus, it can increase effiecincey at higher speeds where the cooler outside air will be rammed into the snorkels.

 

Well said I 100% agree !!

 

That is very true, but I was not sure if the open element would just flat-out draw in more air than the dual-snorkel, negating the effects of the hot air being drawn in. But how would the car be more efficient at high-speeds w/ the dual-snorkel?
Another question: Is the stock-tubing decently sized to handle enough air, or should I up the tubing size?

 

Well, i could be wrong, since i never had a dual snorkel, but it appears as if it should act very similar to ram air. Cold air being forced into the air intake when driving at higher speeds. Air gets cooler the faster it moves. You know what im trying to say. I cant explain crap good in words for some reason. lol.

 

^lol, ya I get what your trying to say. Especiallyo since where the intake is actually located, it is basically a LID for an LS1 car the way it sucks the air up

 

in my opinion the air cleaner itself is not so restricive as to significantly benefit from an open element, the flow rate is probably increased by a minimal amount however the dual snorkel (at first i thought u meant the h.o. dual snorkel, not the tpi snorkel) is superior simply by design, it draws cooler air and more of it. thats my two cents
